Now this is a short list: Deadline reports that Noam Murro and Jaume Collet-Serra are competing to direct 300: Battle of Artemisia, the 300 spin-off formerly known as Xerxes. Murro only has one feature credit to his name (Smart People), but he's set to direct Die Hard 5, should that ever get moving; Collet-Serra directed Unknown, and has the Dracula hunter thriller Harker on deck. Not exactly Joss Whedon vs. Louis Leterrier, but it will have to do. [Deadline]
